Improvement of BSFC by Reducing Diesel Engine Cooling Losses with Emulsified Fuel 962022

This paper describes how cooling loss reductions influence engine performance with emulsified fuel operation. The cooling loss ϕw during combustion was determined from the gas pressure in the cylinder at various conditions and the cooling water loss ϕc through the whole of the engine cycle was measured by changing the cooling water temperature.
It was found that the indicated thermal efficiency varies with the change in cooling loss ϕw and cooling water loss ϕc versus the change of cooling water temperature. As a feature of emulsified fuel combustion it was determined that the reduced cooling loss improves the indicated thermal efficiency.
